Keyword install is when user goes to google play page with your keyword, finds your app, click on it, installs your app..
This kind of installs push your app in this ranking (with this keyword)... all process is automated and controlled by service (in this case - keyapp.top)
DO NOT USE KEYTOP OR ANY SIMILAR SERVICE.
At least for new apps in my case.
This is my experience:
I tested few installs from them first they did not show everything in g.play statistics probably about 40%
Rest has been deleted or ignored.
Maybe the 40% will be also deleted in the new few days.
My app vanished from search results.
I search with exact name, developer name.
Keyword Install means that your app is installed through search in Google Play Store. To be more specific the people you pay will use the keyword you have given them to search for your app and install it only by this method so that your app will increase in ranking for that keyword.
hmmmm, after tests I see jumping from 30-50 position every day, ill try to with another app, thx keyapp.top for chance to test it for free (however Ill be honest, if any trouble with app because it, ill note it)
